For Red Sox, it's case closed with Koji Uehara

Another one in the books. (Jim Rogash)

Smiles and high-fives have become commonplace around Fenway Park these days, but nobody has grinned wider and slapped hands more enthusiastically than the guy most often on the mound at game's end.

Koji Uehara, the 38-year-old Japanese import acquired by Boston as a free agent in December, has been near-perfect during the past two months as a closer for the surprising Red Sox. He compiled a 0.00 ERA in both July and August, and after blowing a save against the Angels on July 6 allowed just six hits in 23 innings over his next 20 appearances.

Uehara now has 15 saves on the season, and has been perfect in 13 of the 15. He is so reliable and so economical with his pitches that last week he was twice called upon by Boston manager John Farrell in the eighth inning to register four-out saves (converting both perfectly).

Sometimes Uehara gets a hand in the dugout.

As a result of his brilliant run, which came after three blown saves in his early days in the role, Uehara has lowered his season ERA to 1.17 and his WHIP to 0.630 -- numbers that along with his 82 strikeouts and 9 walks over 60.1 innings compare very favorably to Jonathan Papelbon's stats during his All-Star career as Boston's closer from 2005-2011. In fact, Uehara's stretch of 20 scoreless games in relief is just one behind Papelbon's best (21 in 2011) and five short of Daniel Bard's club record (set the same year).

In contrast to Papelbon, who had a blazing fastball that neared 100 miles per hour in his heyday, Uehara relies primarily on a forkball and a four-seam heater that tops out around 90. Like Mariano Rivera's cutter, batters know the forkball is usually coming but can do little with the knowledge. Batters swing and miss Koji's offerings 17.2 percent of the time, the top mark in the major leagues.  

Certainly nobody has as much fun finishing games as Uehara, who was primarily a starter during an excellent 10-year career in Japan. Each time he completes the final out of a contest, he pumps his fist, lets out a shout, and then sprints over to his teammates to dole out his high-fives. 

Uehara has a bit of the Bird in him.

For those of us old enough to remember, he is a throwback to Mark "The Bird" Fidrych -- who displayed similar mannerisms during his all-too-brief heyday with the Tigers in the late 1970s. But unlike Fidrych, who was a 21-year-old rookie when he emerged on the national scene, Uehara is grabbing the spotlight with his boyish energy at an age most pitchers are winding down.

Making his run even more impressive is that Uehara -- more often a setup man during four previous big-league seasons -- was Boston's fourth choice as closer this season. Joel Hanrahan and Andrew Bailey both suffered injuries, and fellow Japanese League veteran Junichi Tazawa struggled in the role.

Now that he's gotten his chance to do his hand-slapping on the field at game's end rather than primarily in the dugout after the seventh or eighth innings, Uehara would like to keep doing so as long as possible. 

Numbers that define the resurging Red Sox

Another home-plate celebration.

Boston sports fans coming off their Stanley Cup hangovers are beginning to notice the Red Sox again, and what they are seeing is a team defying all expectations. In fact, the Sox are on pace for one of the greatest single-season turnarounds in franchise history.

With exactly half the season (81 games) gone, the Red Sox entered last night game against the Blue Jays with a record of 48-33. They then won again, and assuming they keep the same pace through the second half, they would wind up with a mark of 96-66 -- a 27-game improvement over the dreadful 69-93 slate turned in by the last-place Boys of Bobby Valentine in 2012.

A shift of that many wins over two full seasons has never occurred in Boston since the MLB schedule expanded to 162 games in 1961. The closest were the "Impossible Dream" Red Sox, who went from a 70-92, ninth-place finish in '66 to a 92-70 mark and the seventh game of the World Series a year later. 

As with all things baseball, numbers tell a big part of the story. Here are some that help define the Red Sox resurgence (all stats through Friday):


22-7
Boston's record in games started by Clay Buchholz (9-0) and Jon Lester (8-4).

Buchholz has licked the competition when healthy.

Although Lester has struggled during much of the last month, and Buchholz has missed several starts while on the disabled list, Boston's two top starters have rebounded nicely from 2012, when the team was a combined 28-34 when they took the hill. 

Buchholz has been particularly intriguing, pitching before his neck injury better than any Red Sox ace since Pedro Martinez -- including a league-best 1.71 ERA and 81 strikeouts in 84 innings. How quick and how well he comes back will be a huge factor in Boston's ability to stay atop the AL East.


2.99
John Lackey's ERA over 13 starts

John Lackey -- finally back on track?

No misprint here. Lackey, who missed all of last season after Tommy John surgery, was the poster boy for bad performances in 2011 with a 6.41 ERA and 1.62 WHIP that had stat geeks scouring their record books to see how he ranked among the worst starting pitchers of all time. 

Here's the funny thing; Lackey actually went 12-12 that year, and is currently just 5-5 after his best outing of this year --  a 7-inning, 12-strikeout, 0-walk gem against Colorado. He's throwing faster and smoother than he has since his glory days with the Angels, and if he keeps it up he won't stay at .500 for long.

2.33 over 92 2/3
Combined ERA and innings for Junichi Tazawa, Craig Breslow, and Koji Uehara

Uehara shuts the door.

Relief pitching was expected to be a strength for Boston, and for the most part it has been -- with Tazawa, Breslow, and Uehara providing an excellent bridge from starter to closer. Unfortunately the end of the bridge -- aka the closer -- has been very treacherous. 

Several  pitchers have failed in the role, most recently Andrew Bailey. Uehara was given the job this week, and is a perfect 3 for 3 in save situations thus far. That plus his 48 strikeouts in 33 innings and WHIP of 0.79 suggest Boston may have finally found the successor to Jonathan Papelbon.

63 and 424
Boston's stolen base and runs scored totals

Daniel Nava -- a surprising star scores again.

When introduced as the new Red Sox manager before this season, John Farrell promised that he would have a hustling ball club. That has surely been the case, as Boston leads the American League in steals -- paced by Jacoby Ellsbury's MLB-best 32 -- and tops the majors in runs scored (by a huge gap over second-place Baltimore). 

The Sox also pace the AL in  RBI (414), OBP (.350, tied with Detroit), and OPS (.796). Throw in their league-leading 179 doubles and 23 triples, and their 309 walks (second to only Oakland), and it's pretty clear these guys know how to get on first and move their way around from there.


.318, .610, 1.017
Average, slugging, and OPS figures for David Ortiz

It's been rip city for Ortiz since coming back.

Nobody knew quite what to expect from Ortiz in 2013. Big Papi missed all but one of the last 72 games last season with a right Achilles injury, and was out for all of spring training and the first 15 contest this year as well. The whispers were that age and his big physique were taking their toll.

What Ortiz has done to answer the critics is hit nearly as well as in his peak seasons of 2004-06. Visibly slimmer than he's been in ears, he has 16 homers and 57 RBI in just 63 games -- despite being intentionally walked 20 times already this year. His next double will be his 500th, and the way he is hitting now, 500 homers may not be out of the question (he has 417).



81 of 82
Number of games Dustin Pedroia has played

Another web gem for Petey.

Pedroia has always played hard, but his aggressive style has sent him to the disabled list on several occasions. This year the scrappy second baseman has been healthy all season, and is at the top of his game -- playing better than ever defensively and performing like a true No. 3 hitter with a .323 average and a 40-double, 90-RBI pace. 

Pedroia was the American League MVP in 2008, but so far is having an even better year in 2013. Fans never know what great web gem or clutch hit they are going to get from The Laser Show, but the chances are they'll get one every game.


.419 (52 for 124)
Jose Igelsias' batting average and hits/at-bat totals

Yup, he's still officially a rookie.

These might be the most shocking numbers of all to emerge from the Red Sox boxscores. Iglesias was a slick-fielding shortstop but a .266 hitter (with no power) in the minors last year, and was just above the Mendoza Line at .202 when recalled from AAA Pawtucket a month ago to fill in for an injured Stephen Drew. 

Management hoped Iglesias could improve on his 8-for-68 stint in the majors last year, and accepted that his glove would make up for an average in the sub-.250 range. Instead, he has been spectacular at the plate, amassing an 18-game hitting streak and reaching base in 29 of 33 games. He's even added a bit of power.

Will Middlebrooks has slumped badly at third, so when Drew returned a few weeks back Farrell decided to let Iglesias stay in the regular lineup by switching him over to the hot corner and sending Middlebrooks back to the minors. Jose has adjusted immediately to the new position.

Can he stay above .400 for a full season? It's very doubtful, but if he can accumulate enough at-bats in the second half, he may make it a very interesting September in the AL batting race.
