Gives up two runs in no-decision
PChicago White Sox
September 29, 2019
Detwiler gave up two runs on five hits and one walk while striking out three through 5.1 innings in a no-decision against the Tigers on Sunday.
ANALYSIS
Detwiler gave up a home run in the first inning, but he only allowed one run in his final 4.1 innings before exiting the contest. Detwiler was making the start on only three days rest, so it was a respectable effort to make it through 5.1 frames. The 33-year-old finishes the season with a 3-5 record with a 6.59 ERA and 46 strikeouts through 69.2 innings.

Detwiler had two years as a decent starting pitcher, but the last four seasons have been a disaster, as he's failed to deliver anything close to acceptable numbers. The left-hander has not punched out more than 6.3 batters per nine in any of his eight seasons and hasn't even shown control to make us care less about that. If he's going to serve as a reliever, he's going to rely an awful lot on contact -- something fantasy players shouldn't want from someone in a role without saves or holds. Perhaps he could gain a modicum of deep-league value if he's deployed almost exclusively against left-handed batters, whom collectively he's held to a sub-.235 average in each of the past three seasons, but don't bet on it. Detwiler signed with the Athletics on a minor league deal over the offseason, although he still seems to be in line for an organization depth role.
Detwiler spent last season in the Nationals' bullpen and failed to make any kind of impact, posting a 4.00 ERA and 1.41 WHIP with a very weak 39:21 K:BB ratio in 63 innings. Left-handers who can crank their fastballs up to 95 mph will always get plenty of chances to prove they belong in the majors, but as with seasons prior, Detwiler's reluctance to use his curveball or changeup (he threw his fastball 86% of the time, which was actually down a couple of ticks from 2013) leaves him with no margin for error, even in a relief role. The Nationals, with younger arms coming up and pushing for spots on the staff, shipped Detwiler to the Rangers, who will stretch him back out as a starter. You can never say never with a talented arm, but there's no reason to make any fantasy investment in Detwiler until he shows some kind of spark.
An oblique injury and back woes limited Detwiler to just 13 fairly ineffective starts last year, and there's been some talk of moving him to the bullpen. That's got more to do with the Nationals' struggles to find a reliable relief lefty in 2013 than it does Detwiler though, and the most likely scenario still sees him breaking camp as the club's No. 5 starter. He doesn't have the raw stuff or pinpoint control to put up huge numbers in that role, but with a good defense behind him and what should be a solid offense around him, he'll have some value.
Detwiler finally established himself as a bona fide major league starter in 2012. He does not get a lot of strikeouts, but succeeded thanks to a 50.8 percent groundball rate and an infield full of potential Gold Glovers behind him. That kind of success can be hard to maintain, and he certainly does not have the fantasy upside of his more celebrated rotation-mates, but as long as the Nationals have the likes of Ian Desmond, Ryan Zimmerman and Danny Espinosa scooping up those grounders, Detwiler will have a pretty good safety net.
Detwiler missed the first half of 2011 recovering from hip surgery, but he posted a good second half in the back of the Nationals' rotation. He features a fastball that averaged 92.2 mph last season, a change-up (his best pitch) and a curveball. Detwiler pitches to contact, and his .272 BABIP was a major reason he kept his ERA below 4.00, and his 24.2 line drive rate shows that opposing hitters hit the ball well. As of now, Detwiler looks as if he will compete for the fifth spot in the Nationals' rotation for 2012, and will probably bounce between the rotation and bullpen for most of the season.
A hip injury scuttled Detwiler's season, leaving him rusty and ineffective even when he did make it back on the mound at the end of the season. The only real success he's had over the last few years came in a six-start stint at Double-A in 2009, and while he'll get a look this spring it's hard to have any confidence either in his ability to stay healthy, or his ability to get out major league batters when he is able to pitch.
Detwiler's 2009 was a mixed bag. He pitched at three levels, finishing the season in the big league rotation, and while his control held steady at all three stops he got more hittable and missed fewer bats the higher he climbed up the ladder. Overall, though, he did a solid job of keeping the ball down and in the park, and barring an offseason spending spree by GM Mike Rizzo or a disastrous spring Detwiler should begin the season as the Nationals' No. four or No. five starter. He's just 24 and still has plenty of ceiling given his low-90s fastball and solid offspeed pitches, and with all eyes on Stephen Strasburg, Detwiler may just fly under the radar this season.
Detwiler's first full pro season was highlighted primarily by control issues, both inside and outside the strike zone, that made general Jim Bowden's brief dalliance with the idea of keeping him in the big league bullpen out of spring training look very silly. Detwiler still has good stuff though, and might yet get his fastball up into the mid-90's once he fills out. While he probably won't fly up the ladder, he still looks like one of the Nationals' top pitching prospects.
The Nationals' top pick in 2007, Detwiler saw limited duty in the minors as the organization was worried about his previous college workload, but he also pitched an inning in the majors in September. The left-hander has three quality pitches including a fastball that can touch the mid 90's and a hard curve, and while he dominated the Gulf Coast League in his brief stint there he was far less impressive at High-A. Expect him to begin 2008 back at High-A, with an eye towards making his 'real' big league debut in 2009.
