Angels left-hander Tyler Anderson has had a shaky season, and the 35-year-old southpaw tells Jeff Fletcher of the Orange County Register that he’s been playing through a back injury throughout the year. Anderson’s most recent start was pushed from Tuesday back to Saturday in order to afford him some extra rest. Anderson described the discomfort as “on and off” but generally something he’s been able to pitch through. However, he acknowledged that it “flared up probably the worst it had been” this season after his most recent outing.
Anderson was tagged for four runs in four innings against the Rays in said start. That marked his sixth time in the veteran southpaw’s past ten trips to the mound that he yielded at least four runs. His ERA over that span is an unsightly 5.50 and has ballooned his season-long mark from 3.99 to its current 4.63.
This is the final season of Anderson’s three-year, $40MM deal with the Halos. At the time, it was the first multi-year deal for a free agent starting pitcher that owner Arte Moreno had authorized in a decade (though the Angels have since signed Yusei Kikuchi to a three-year deal as well). It’s not a promising note on which to end his season, though Anderson will hope that the extra rest can help him get back on track for a strong finish.
Anderson is far from the only struggling member of the Angels’ rotation. Righty Jack Kochanowicz has been optioned twice within the past month, understandably so after turning in a grisly 6.19 ERA with a 14.5% strikeout rate and 11.3% walk rate in 107 2/3 innings spread across 22 starts.
The struggles from the 24-year-old Kochanowicz have prompted a rotation change with some permanence. Another 24-year-old righty, Victor Mederos, appears set to serve as the Halos’ fifth starter for the time being, per Fletcher. The right-hander changed his arm slot and pitch mix this year, most notably swapping out his four-seamer for a sinker, and he’s found strong results in the upper minors thus far.
While Mederos has allowed five runs in eight big league innings, he’s sporting a 3.41 ERA in the hitter-friendly Triple-A Pacific Coast League. He’s not missing tons of bats (19% strikeout rate) but is sporting roughly average walk and ground-ball rates. Opponents have struggled to make hard contact against the righty, and he’ll get some opportunities to show he can stick on the big league staff down the stretch.
On the injury front, the Angels will be without outfielder Gustavo Campero for a significant period — perhaps the rest of the season. The 27-year-old was carted off the field with a lower-half injury earlier this week. He’s avoided a catastrophic injury, thankfully, but has still been diagnosed with a high ankle sprain, MLB.com’s Rhett Bollinger reports. The team hasn’t formally ruled Campero out for the rest of the year, but there’s a chance he won’t be able to make it back to the field.
In brighter Angels injury news, right-hander Robert Stephenson is setting out on a minor league rehab assignment today. Stephenson tells Erica Weston of FanDuel Sports West that he’ll make appearances with the Angels’ Triple-A club today and again on Sunday.
Stephenson, 32, signed a three-year, $33MM deal with the Angels in the 2023-24 offseason but missed the entire ’24 campaign due to Tommy John surgery. He briefly returned earlier this summer but pitched only one inning before heading back to the injured list — this time due to inflammation in his right biceps. He’s since been moved back to the 60-day IL but now finally appears to be nearing a return.
Stephenson’s rise from journeyman DFA candidate to high-leverage standout in 2023 was rapid. He was designated for assignment by the Rockies late in 2022, claimed off waivers by Pittsburgh and, in 2023, was flipped from the Pirates to the Rays in a minor June swap for minor league infielder Alika Williams.
While Stephenson had long proven capable of missing bats at a high level, he never put it all together until that trade to Tampa Bay. In 38 1/3 innings with the Rays, he posted a 2.35 ERA while punching out a colossal 42.9% of his opponents against just a 5.7% walk rate. Stephenson was averaging 96.8 mph on his four-seamer, and his gargantuan 24.8% swinging-strike rate (28.9% with the Rays) was the highest single-season mark by any pitcher (min. 40 innings) since Brad Lidge’s 25.1% mark back in 2004.
The first two years of that sizable free agent contract will go down as a wash, by and large, but if Stephenson can finish the year on a high note, it’d give the Angels a bit more optimism regarding their bullpen heading into the 2026 campaign.
