2022 Fantasy Outlook

Guerra entered 2021 with low expectations after logging just eight combined big-league innings during the previous two campaigns. To the surprise of many, he became one of Oakland's most trusted relievers as the season progressed. The 32-year-old ended the year with a decent 4.11 ERA, 1.11 WHIP and 62:20 K:BB across a career-high 53 appearances (65.2 innings), and those numbers would have been much better had it not been for a rough final month. Utilizing a five-pitch mix, Guerra dominated with his sinker, curveball and newly-developed cutter, as hitters went a combined 5-for-56 against the three offerings. With the Athletics' relief corps having plenty of moving parts entering 2022, Guerra appears to be one of the few arms with a firm grasp on a bullpen spot. Lou Trivino is the frontrunner to open the campaign as the team's closer, but Guerra poses a strong case to see high-leverage work right out of the gate. Read Past Outlooks

Elbow

April 13, 2022

Guerra underwent reconstructive surgery on the UCL in his right elbow Wednesday, Matt Kawahara of the San Francisco Chronicle reports.

ANALYSIS
The A's announced Guerra's elbow procedure last week, but it wasn't previously specified as Tommy John surgery. The 32-year-old will miss the rest of the season and likely the first half of the 2023 campaign while going through his recovery and rehab.

2008

2007

Guerra was designated for assignment for the second time following the 2015 season, but the Angels opted to take a chance on him with a Rule 5 draft pick. Although he didn't stick with the club in that capacity, he did manage to make his mark at the major league level. On the heels of just three strong appearances with Triple-A Salt Lake, the big reliever carved out a major role in the Angels bullpen thanks to his impressive control (1.2 BB/9). Although his 6.1 K/9 wasn't anywhere near as good as it was in the minors, the right-hander managed to get batters out without the whiffs to finish the season with a quality 3.21 ERA and 1.11 WHIP. Guerra appeared to be poised to enter 2017 as a middle reliever for the Angels prior to being designated for assignment in February, but his inability to miss bats should preclude him from climbing back to the majors very soon.

Guerra's conversion from former top starting pitching candidate to reliever hit a speed bump last season at Triple-A and he was even removed from Minnesota's 40-man roster in the offseason. Guerra had another strong strikeout rate (8.8 K/9), but did not have great control and had a 4.48 ERA. He did have a high BABIP (.331), so he could rebound. Since he will turn 24 this season and with the Twins dropping him from the 40-man roster, his window to become an impact player in the majors may have closed.

Guerra had an ugly 5.09 ERA at Double-A New Britain, but his cosmetic numbers hide a turnaround that could give him a shot at a big league bullpen job as early as 2012. Guerra struggled to begin the season at Double-A, but improved dramatically when moved to the bullpen with a 2.81 ERA and 36:8 K:BB ratio in 32 innings after the All-Star break. He also had an outstanding 95:28 K:BB ratio in 95 innings along with a 3.72 FIP (which may have indicated he was unlucky). His work as a reliever made such a strong impression that he was being considered for a September callup to Minnesota before being sidelined by forearm soreness. He could contend for a role in the majors with a strong start at Triple-A. He'll turn just 23 years old next season, so there's some upside if he can sustain the strikeout rates and control he found as reliever.

Guerra looked like he turned the corner in 2009 to perhaps become a top prospect, but he seemed to regress last season with a 6.31 ERA and unimpressive 90:49 K:BB ratio in 133.1 innings (just 6.0 K/9IP) between Double-A and Triple-A. He'll be just 22 years old this season and young for Triple-A, but he'll need better strikeout rates and control to think he'll be an impact player in the majors.

Guerra was thought to be the hidden jewel in the Johan Santana trade, but then looked like a bust after a disappointing 2008 season. However, he turned the corner in 2009 with a 106:42 K:BB ratio in 149 innings between High-A and Double-A (despite a 4.89 ERA). He had a 49:18 K:BB ratio in 63.2 innings at Double-A as a starter. He'll be just 21 years old next season and could advance rapidly since it looks like he's finally putting things together after he was probably rushed earlier in his career (playing at High-A at age 18).

Guerra was thought to be the hidden jewel in the Johan Santana trade, but disappointed at High-A Fort Myers amid reports of a decline in velocity and a lack of movement on his fastball. He still hits the low 90s with his fastball and has a plus changeup, but struggled with his control - allowing as many walks as strikeouts. Still, he was just 19 years old while playing in High-A and is still seen as somewhat raw after missing time earlier in his career with injuries. Even so, he'll need a strong season to return to the upper ranks of Minnesota's prospects.

Guerra is looking like a bargain at the $700K the Mets paid to sign him in 2005 as he's now potentially Minnesota's best pitching prospect after coming over in the Johan Santana trade. Guerra missed more than a month last season with what was described as shoulder tendinitis, but was eased back into action with a limited workload for the next few months. He improved the velocity on his fastball to 89-94 mph, topping out around 96, and has a plus changeup - which is thrown with the same arm action as his fastball. When his changeup is working, he gets a lot of swings and misses on it (similar to Johan Santana), but Guerra still needs to work on developing and refining his curveball. Guerra has only thrown 179 innings in the minors, largely due to his injuries and being brought along slowly by New York, so the next step is for him to make it through a full season unscathed. He should begin 2008 at High-A and a late-2009 ETA seems reasonable.

Guerra showed why the Mets paid $700K to sign him in 2005 as an 18-year old by rebounding from an 0-3 start for Low-A Hagerstown to finish the year at High-A St. Lucie. Guerra limited hitters to a .213 batting average against and .291 slugging percentage while striking out 63 in 77.2 innings pitched at St. Lucie. His fastball is his best pitch and the key for him going forward is to control his curveball and changeup, which is thrown with the same arm action as his fastball. When it's working, he gets a lot of swings-and-misses on it. Look for Guerra to start 2007 at St. Lucie and possibly see Double-A Binghamton by the end of the year as he is considered one of the Mets' top pitching prospects.
