If you're a fan of one of these teams, you know of what I speak. For all the hype and attention given to the trade deadline, the biggest area of improvement for playoff contenders usually needs to come from players already on the roster. Here are 10 who need to step it up:
Ervin Santana, Angels (4-10, 6.00 ERA)
At this point, I'm not sure why the Angels are still running Santana out there. Simply replacing him with any decent fourth or fifth starter would be a huge improvement, and you wouldn't have to pay the hefty price to acquire, say, Zack Greinke. (Although adding Greinke would certainly bolster the playoff rotation.) After a terrible April in which he surrendered 10 home runs, Santana pitched a little better in May and June, but has been trending downward lately. In his past four starts he has a total of four strikeouts.
Santana's numbers are down across the board -- higher walk rate, lower strikeout rate, way too many home runs -- but it appears his primary problem has been too many hanging sliders. In 2011, batters hit .161 with seven home runs off his slider; this year they're hitting .199 but with 12 home runs already. Overall, he's allowed 23 home runs, despite pitching in a good pitcher's park.
Andre Ethier, Dodgers (.289/.362/.481)
I mentioned Ethier in Wednesday' blog about the Dodgers. While his overall numbers are solid, since May 22 he's hitting .259/.346/.377 with just two home runs in 45 games. The Dodgers need more production from their cleanup hitter.
Jemile Weeks, A's (.216/.302/.300)
While the A's might look to boost their offense by adding a shortstop or third baseman (good luck with those positions), they'll likely ride with Weeks at second. So promising as a rookie in 2011 when he hit .303 with 26 doubles and eight triples in 406 at-bats, Weeks has actually doubled his walk rate while striking out less, but a .248 average on balls in play has hurt him. That's not all bad luck -- he's hitting fewer line drives and more groundballs than last season, and clearly he isn't driving the ball much. But the talent is there to have a strong final 60 games.
Reds leadoff hitters (.200/.247/.304)
That's mostly courtesy of rookie shortstop Zack Cozart with Drew Stubbs appearing there a few times of late. But that means Dusty Baker usually just moves Cozart down to the No. 2 hole. So, yes, Baker apparently believes it's a good idea to start your lineup with two sub-.300 OBP guys hitting first and second. He just doesn't get it, and why the front office hasn't told him to stop that nonsense is beyond me. The Reds would be better off with Brandon Phillips and Jay Bruce hitting 1-2. At least that way your better hitters are getting more plate appearances.
Michael Young, Rangers (.270/.299/.346)
For all the talk about the Rangers seeking another starting pitcher with Colby Lewis out for the season and Roy Oswalt struggling, Young is the one guy in the lineup who's been a big, fat zero. As a designated hitter with an empty .270 batting average despite playing in the best hitter's park in the American League, Young has been one of the least valuable hitters in the league. In fact, based on Baseball-Reference offensive WAR, only Ryan Raburn and Justin Smoak rank worse than Young. And he's getting worse; he hit .326 in April, but has a .270 OBP in July and hasn't homered since May 7.
Tim Lincecum, Giants (4-11, 5.88 ERA)
This one goes without saying. After two good starts (against the Triple-A Astros and Phillies), Lincecum was roughed up again on Wednesday, allowing 11 runners and two home runs to the Padres in less than five innings. I don't want to hear about his FIP or xFIP -- Lincecum has been terrible, can't locate his fastball, and when he does throw strikes he gets lit. The potential is there for improvement, of course, but it's starting to look more and more like a lost season. The Giants will undoubtedly look to upgrade the offense -- amazingly, Bruce Bochy hit Brandon Crawford fifth on Wednesday -- but Lincecum could provide a bigger left than any hitter they might acquire.
Philip Humber, White Sox (4-5, 6.25 ERA)
Was that this year that Humber threw his perfect game? The White Sox are still hoping that John Danks can return at some point, but considering he just threw 20 pitches off a mound on Tuesday in testing his left shoulder, he's still a long ways away. Humber has been burned by the long ball (16 home runs in 76.1 innings).
Tommy Hanson, Braves (11-5, 4.39)
Hanson's win-loss record is nice thanks to great run support when he's started, but he's hardly pitching like an ace right now, with a 5.54 ERA over his past 11 starts while averaging less than six innings per start. Maybe that hasn't resulted in losses, but it has taxed the bullpen. Injuries have cut into Hanson's once-promising potential, and the truth is his stuff doesn't grade out as high as it once did. His average fastball velocity is down 3 mph from where it was two seasons ago, and he now sits around 90. He's allowed 19 home runs this season -- 15 off his fastball.
Cardinals bullpen (10-15, 4.17 ERA)
This story sounds familiar: It took the Cardinals four-plus months last season to figure out their bullpen. The Cardinals rank 10th in the NL in bullpen ERA, and all the teams below them have losing records. Cardinals relievers have allowed 34 home runs, third-worst in the league; only the Rockies and Astros have allowed more. The arms and ability are here, as we saw last October.
You can take apart the Red Sox a thousand different ways -- injuries, clubhouse issues, Bobby Valentine and so on -- but consider this: Despite the multitude of injuries, the Red Sox are still second in the AL in runs scored. If these two were instead 8-5 and 9-5, they'd be 56-43 and 3.5 games behind the Yankees instead of 4.5 out of the wild-card standings.
