The Arizona Fall League came to a close a couple days ago.  Here is how some Mariner prospects came out.

Winners:

Carlos Triunfel: Seattle’s top prospect ended an up and down stint in the AFL with a .298/.339/.394 final line in 104 at bats.  This is very encouraging, considering that the AFL is advanced ballplayers with experience in the upper levels of minor league baseball.  Triunfel hasn’t yet experienced AA, doesn’t turn 19 until February and was the youngest player in the league.  The shortstop also spent time at second and third base.

Doug Fister: The right hander managed to put up a 3.32 ERA in 19.0 innings pitched in the dry desert air.  He gave up a lot of hits (20), but kept out of trouble with a decent K/BB ratio of 20/7.  Fister has started for the majority of his career, but most think his future is in the bullpen, and he could contribute as early as next season.

Losers:

Greg Halman: The best athlete in the organization struggled mightily in his first AFL performance, hitting just .211/.244/.410 in 83 at bats.  He showed zero improvement in his plate discipline, striking out 32 times while walking just twice.  That is simply unacceptable, and hopefully the organization will finally do something about it as he advances through the upper levels of the system.  He did show off his tremendous power, however, smacking nearly half of his hits for extra bases (3 HR, 3 2B, 2 3B).

Stephen Kahn: Kahn did nothing to justify his recent promotion to the 40-man roster, posting a 8.79 ERA in 14.1innings pitched, thanks to 18 hits, 4 homers, and 9 walks in that span.

Gaby Hernandez: 7.67 ERA in 29.1innings, including 5 homers and 14 walks.

Joe Woerman: 8.71 ERA in 11.1innings.  18 hits, 2 homers, 6 strikeouts and 9 walks.

Rob Johnson: Not known for his hitting, backstop hit .229/.260/.396 in 48 at bats.

Don’t put a ton of stock in the pitcher’s performances, because the ball flies out of the park thanks to Arizona’s complete lack of humidity.  Halman is by far the biggest disappointment, with Triunfel’s performance being the most impressive.
