Mobile Mariners Aid Pitching Staff

During the offseason, we touched upon the absolutely ridiculous range of the Seattle Mariners’ new outfield. With imports Endy Chavez and Franklin Gutierrez joining Ichiro Suzuki out in the pasture, the M’s figured to possess three center field-worthy gloves to cover the gaps (Ken Griffey Jr. has since been added, to fill the Raul Ibanez comedic relief role).

The potential gain of a Chavez/Gutierrez/Suzuki alignment over Seattle’s consortium of laggardly leather in 2008 is huge, with a swing of perhaps 5 wins (more, if Chavez continues to see the field regularly). Granted, some of those gains will be returned in the hitting department, but the stable of fleet-footed defenders had to be a welcome addition to a pitch-to-contact rotation (M’s starters ranked 22nd in K/9 in 2008, with 5.92).

While Ichiro (ulcer) has only recently returned to the field following his first ever DL stint, Chavez and Gutierrez have put on a clinic in left and center. In ’08, the Mariners’ outfield posted a collective -4.6 UZR/150, meaning that Seattle’s fly-catchers were about five runs worse than average per 150 games played.

In 2009, the M’s outfield has compiled a spit-take worthy 56.9 UZR/150, lapping the field by a significant margin (the Rockies are currently second, with 36 UZR/150). Granted, we are talking about a small sample of games, and no bold claims should be made on defensive numbers in mid-April, but the change in quality has been nothing short of stunning.

Currently, Mariners pitchers have allowed a .128 Batting Average on Balls in Play on flyballs in 2009 (the A.L. average thus far is .230). Last year, M’s hurlers posted a .213 BABIP on flyballs (.215 league average).

Short of finding a way to clone Willie Mays a couple of times, it would be hard to keep up that pace. But, Seattle’s outfield trio comes with glowing scouting reports and the numbers to back them up. Strikeout-challenged starters such as Jarrod Washburn and Carlos Silva might not look quite as bad, with so many balls put in play being converted into outs, and the resurgent Erik Bedard is slanted toward the flyball end of the pitching spectrum.

Outfield defense might not seem like a big deal from a fantasy perspective, but having quality defenders behind a pitcher can be the difference between a guy being roster-worthy or simply waiver fodder. With Chavez, Gutierrez and now Ichiro manning the outfield, whomever takes the mound for the M’s does so with a leg up on the competition.
