Brent Rooker was an All-Star in 2023 (even if it felt like an “everyone gets a trophy” moment just so the A’s had a representative), a season in which he hit .246 with 30 homers, 69 RBIs, 61 runs and a .817 OPS. (He also struck out 172 times, but more on that later.)
Rooker started this year slowly, hitting .206 with five homers, 13 RBIs, 31 strikeouts and a .769 OPS in March-April. This month has been a totally different ballgame with the 29-year-old hitting .377 with five homers, 15 RBIs, 13 runs and 1.186 OPS in 14 games. (Those numbers looked even better before going 1-for-12 in three games before Friday.)
This hot stretch made Rooker the most added player in ESPN leagues over the past week, which begs the question: Is he for real or is he just another hot power hitter who will disappear from fantasy relevancy before you have the chance to see if he is available in your league?
Among players with a minimum of 130 plate appearances, Rooker entered Friday tied with six others for the fourth-most homers, and ranked fifth in slugging percentage, 24th in RBIs, 30th in on-base percentage, 33rd in average and was in the top 50 in walk percentage.
His Statcast page shows a ton of red, as he ranks in the top 8 percent of the majors in exit velocity and maximum exit velocity, and the top 2 percent in xSLG. He is in the top 3 percent in WOBA and the top 4 percent in xWOBA. He also is in the 85th percentile in hard-hit rate and the 93rd percentile in barrel percentage. His contact numbers have improved, too.
Despite all that, though, there are concerns this hot stretch is nothing more than another streak from a power hitter who has a Cal Raleigh with a better average vibe. (In 2023, Raleigh hit .218 with 30 homers, 75 RBIs, 78 runs, a 10.7 percent walk rate and 34.7 percent strikeout rate in 145 games. Rooker hit .246 with 30 homers, 69 RBIs, 61 runs, a 9.3 percent walk rate and 32.7 percent strikeout rate in 137 games. Raleigh and Rooker entered Friday with 10 homers, 21 runs and similar walk and strikeout rates.)
Rooker’s 31.4 percent strikeout rate is the 14th-worst in the majors, and that is going to make him virtually unusable at times (hitting in a weak A’s lineup doesn’t help either). And, it’s happened before.
Rooker started out hot in April 2023, hitting .353 with nine homers, 22 RBIs, 16 strikeouts and a 1.245 OPS in 22 games. Over his next 56 games, he hit .208 with seven homers, 22 RBIs, 76 strikeouts (35.3 percent of his plate appearances) and a .672 OPS. He hit .198 in May and .191 in June. Over his final 115 games, he hit .228 with 156 strikeouts (35.5 percent).
During this hot stretch to kick off the month, he also had a .417 BABIP, which is not sustainable. But you didn’t need Roto Rage to tell you Rooker, a career .238 hitter, is not going to hit like this the rest of the way.
Here is what you need to know: If you have Rooker on your roster, now is the best time to test the trade market. Or just ride out his hot streak. If he isn’t on your roster, and he is available in your league, and you need a power boost, Rooker will give you what you need (and he won’t completely Raleigh your average).
He has legit power. But, you should make sure your squad has the proper depth for the inevitable cold stretch — because he will go cold.
