BP Annual Player Comments

Year		Comment
2014		Acquired from the Cubs in late July to bolster a beleaguered pitching staff, Guillermo Moscoco was an adequate near-replica of Guillermo Mota. Even got the name about right.
2013		The Royals claimed Moscoso on waivers in November from Colorado, where he'd gone in the trade that sent Seth Smith to Oakland last winter. His fastball sits in the low 90s but has good movement. Following up on a strong rookie campaign in the A's rotation, he bounced back and forth last year between Colorado Springs and Denver, and between starting and relieving. Moscoso was hit hard regardless of level or role, with spotty command forcing him to work behind in the count too often with the big club. He could develop into a serviceable swing man, but at his age, he'd better do it now.
2012		He started 21 games for Oakland, logging 128 innings and offering respectable production despite a lack of overwhelming stuff. Moscoso, a 28-year-old acquired from the Texas Rangers for minor league reliever Ryan Kelly, features a ghost-fastball, a pitch that seems to disappear as it approaches the plate. Thrown with average velocity for a fastball, the pitch butters its bread with intense movement, and thanks to Moscoso’s great extension, the ball appears to explode then disappear as it approaches the plate. It’s a wonder of nature. The rest of his pitches are so-so, and despite the ghost-ball and a minor-league strikeout rate of 8.8, Moscoso fails to miss a lot of big-league bats. His rotational success doesn’t seem overly sustainable, but the ability to throw strikes and log innings could allow the Venezuelan to stick around the big leagues, perhaps even in the rotation if the competition for spots proves thin.
2011		Acquired from the Tigers for self-proclaimed five-tool player Gerald Laird, the right-handed Moscoso spent the majority of the season pitching for the Oklahoma City Redhawks in the Pacific Coast League, but did get to enjoy 2/3 of an inning of hot major-league coffee in 2010 after sampling 14 innings of Agent Cooper-approved joe in 2009. Armed with little more than a phantom fastball with average-to-plus velocity and crazy life, Moscoso looks to be a better fit out of the pen, but spent most of his time in Triple-A working in the rotation. If his curveball can find some consistency, Moscoso might be able to stick on a major-league roster, but his future role is at the mercy of his development of secondary pitches.
2010		The primary player received from the Tigers in return for Gerald Laird, Moscoso has struck out more than a batter per inning in the minors, but not because of a power arsenal. He's more of a trick pitcher, with a 89-92 mph fastball that plays up due both to its natural movement and a highly deceptive delivery that prevents batters from picking up the ball out of his hand. A checkered health record and smallish frame always had scouts projecting him for a bullpen role once he got the to the big leagues, and that was the case when he performed admirably in a pair of auditions with the Rangers. Still, the pitching depth chart is deep in Texas, and he goes into the spring with no guarantees.
2009		Part of the package that netted Gerald Laird from the Rangers, reliever Guillermo Moscoso put up some eye-popping strikeout rates in the minors, but he's more deceptive than overpowering.
