Enrique Burgos has the stuff to be successful, but he needs to cut down on the walks. Last year, he posted a 5.0 BB/9, which was in line with the marks he's posted at every professional stop (Burgos's career low BB/9 was 4.5 at Low-A in 2012). With all the walks, it's no surprise that Burgos has compiled a 1.51 WHIP the last two years at the MLB level. There's no denying that Burgos has an electric arm. His average fastball velocity was 95.7 mph is 2015 and 95.8 mph in 2016. That heater helped Burgos post a 9.4 K/9 last year and he also picked up a save, but Burgos is simply too volatile to trust at the moment.
Burgos was charged with four runs without recording an out after entering in the ninth inning of Wednesday's win over the Braves. With the Diamondbacks up four runs, Burgos came on and promptly gave up a home run. He then walked two batters and gave up an RBI single before manager Chip Hale decided he had seen enough. The inherited runners would come around to score, which saddled Burgos with four earned runs allowed. Arizona would rally to win in 11 innings, but Burgos' performance is concerning. The back end of Arizona's bullpen is a mess right now, and it's unclear who might get the next save opportunity.
Burgos (1-1) blew a save as he allowed a run on two hits in the ninth inning Monday against Atlanta but picked up the win via Paul Goldschmidt's walk-off home run. Burgos is now just 1-for-4 in save opportunities over his last four outings. He was undone by his second home run in that span Monday, a solo blast by Freddie Freeman. Jake Barrett has been struggling too, but Burgos isn't doing much to show the Diamondbacks he deserves high-leverage innings.
Burgos was saddled with his first blown save of the year in Thursday's loss to the Padres. Fellow reliever Jake Barrett started the eighth and proceeded to load the bases. Burgos was called on to get the final out with Arizona up a run, but he gave up a three-run double to Alex Dickerson before retiring the final batter of the inning via strikeout. Barrett has struggled mightily in recent weeks, so despite blowing the save Thursday, Burgos could be in line for more save opportunities moving forward.
Burgos was recalled from Triple-A Reno on Saturday. It could be a short stay for Burgos with Nick Ahmed (paternity) possibly missing as few as three games. Burgos was up for two weeks during his first stint with the big club from late April to early May, allowing six runs on seven hits and four walks in 6.2 innings. Look for Burgos to continue working exclusively in low-leverage spots.
Burgos was optioned to Triple-A Reno on Sunday. Burgos was called up in late April to replace Silvino Bracho's spot, who was optioned down to Triple-A Reno simultaneously. Burgos has since been a reliever for the Diamondbacks, pitching a total of 6.2 innings in seven games for an ERA of 8.1 and four strikeouts. He is used to provide organizational bullpen depth.
