The Athletics sent Jeffrey Springs to the mound Friday in the finale against the Colorado Rockies, hoping to finish a sweep while the game was being played in heat that could punish every pitcher who stayed out there too long. Springs took the ball without a win in two months, and the club still needed him to steady a staff that had already been stretched by the conditions and the series itself.
That is why Willi Castro is showing up in searches tied to this game even though his name is not part of the confirmed lineup or the pitching matchup. The Athletics were still sorting through the same simple questions that mattered most to the finale: who would handle the start, who would get rest, and how long the arms would be allowed to last if the ball kept carrying in the heat. Springs had opened the Las Vegas series and allowed five runs on eight hits over five innings in a no-decision, a line that underlined both his workload and the uneven results that have followed him through 15 starts this season.
On the morning of the game, the Athletics recalled left-handed reliever Brady Basso and optioned Joey Estes back to Triple-A, a move that signaled how much they were managing the bullpen around the series finale. Lawrence Butler was leading off, Nick Kurtz was the designated hitter and Jeff McNeil was at first base, while Carlos Cortes was making his first start of the series in right field and batting fourth. Shea Langeliers sat after two straight days behind the plate, Jacob Wilson got a rest day after recently coming back from the injured list with a shoulder injury and Alika Williams started at shortstop after posting three hits and a walk the previous night.
Springs still carried the tension point that had followed him into the start. He entered his 15th outing at 3-6 with a 4.68 ERA and 63 strikeouts in 75 innings, and his recent trouble keeping the ball in the park made the assignment more fragile than a normal series finale. The Athletics were trying to win for the fifth straight time, but the heat offered little margin for error, especially with a starter who had not won in two months and a bullpen already being adjusted before first pitch.
Tomoyuki Sugano was set to oppose him for the Rockies after going 6-4 with a 4.08 ERA and 39 strikeouts over 68 1/3 innings. He had won his previous two starts and most recently held the Chicago Cubs to three runs on six hits over five innings. If Springs could not work deep enough, the Athletics were going to have to piece the rest of the afternoon together quickly.
