Waiver Wire: September 12th

Jed Lowrie, Red Sox (Owned in 2% of Yahoo leagues)

Dustin Pedroia‘s laser show is postponed until 2011, and Marco Scutaro’s playing through a partially torn rotator cuff in his right shoulder. Thus, Lowrie is getting the chance to re-insert himself into Boston’s plans after scarcely playing at all over the past two seasons.

A 2005 supplemental first-round pick out of Stanford, Lowrie displayed quality secondary skills for a middle infielder in the minors (.284/.380/.445 line in 1,600+ plate appearances). Baseball America ranked the switch-hitter as the #73 prospect in the game prior to 2008, and Lowrie reached Fenway that year. He held his own in the majors, batting .258/.339/.400 in 306 PA with a 95 wRC+. Lowrie punched out often (26.2 K%), but he controlled the zone by walking 11.4% of the time and swinging at pitches thrown off the plate just 17.6% (25.4% MLB average in ’08).

Unfortunately, Lowrie suffered a left wrist injury in 2009 and had to undergo surgery that wiped out three months of his season. He took only 76 trips to the plate in the majors last year, posting a 20 wRC+ with terrible luck on balls put in play. This season, Lowrie was sidelined until late July with Mononucleosis.

Since returning to action, however, Lowrie’s bat has been a plus for the Sox. He’s got a 122 wRC+ in 128 PA, hitting .255/.359/.445. The 26-year-old has a 14.1% walk rate, hacking at 21.9% of pitches thrown outside of the strike zone (29.2% MLB average this season). Lowrie’s no star, but he possesses patience and a dash of pop while capably playing up the middle of the diamond. CHONE thinks Jed is a .262/.347/.400 hitter ZiPS is less of a fan, though (.242/.324/.394). I like his chances of staying closer to that CHONE forecast.

Jhoulys Chacin, Rockies (22%)

For most of his minor league career, Chacin was a moderate-K, ground ball-centric pitcher who limited walks. In the show, though, the 22-year-old Venezuelan native has taken a power approach.

In 113.1 innings pitched this season, Chacin has whiffed 117 batters. His rate of 9.29 strikeouts per nine frames ranks 10th among pitchers tossing at least 100 innings. His 10.7% swinging strike rate also ranks 10th, and his 74% overall contact rate trails just Francisco Liriano. Chacin’s breaking stuff has been devastating. According to TexasLeaguers.com, he’s throwing his low-80’s slider for a strike 70.6% (63.4% MLB average) and getting a whiff 22.5% (13.6% MLB average). The righty’s high-70’s curveball is getting strikes 61% (58% MLB average) and whiffs 14% (11.6% MLB average).

All of those whiffs have come with walks. Throwing 41.3% of his pitches within the zone (46.7% MLB average), Chacin has issued 4.05 BB/9. Even so, he’s boasting an above-average ground ball rate (46.3 GB%) and a 3.69 xFIP. Pick him up if he’s still sitting on the sidelines in your league.
