Plus: finding All-Stars for the Yankees and Mariners, a check-in on early-season surprises and catchers sure are getting hit in the groin a lot more than they used to. I’m Levi Weaver — welcome to The Windup!While You Were Sleeping: A’s get sneak peek of life in VegasThe A’s won’t be in Nevada full-time until 2028, but this week they’re playing six games at Las Vegas Ballpark, currently the home of their Triple-A affiliate.There are, of course, peccadilloes in any minor-league park. The hard infield dirt led to two misplays by Brewers shortstop Joey Ortiz in the third inning of yesterday’s game, which helped the A’s to a six-run inning. As noted by the Brewers broadcast, a second-inning double by A’s shortstop Alika Williams might have gone foul if not for the extremely arid Las Vegas air.And then there were the home runs. Eleven of them.Shea Langeliers hit a 483-foot home run to lead off the game. That’s the longest in MLB this year, giving him the two longest home runs in baseball this year (the previous high was 467 on April 15 against the Rangers). According to the broadcast, that was also the longest home run allowed by the Brewers in the Statcast era (2015-present).Of all the home runs hit last night, the funniest came in the 10th inning, when William Contreras hit a home run and then fell right on his backside.The final result, after 12 innings, was a 15-14 Brewers win. Adding to the chaos: The two teams set a new record with 16 ABS challenges. I’m sure it’s not the wildest ride the city of Las Vegas has seen, but I suspect those new park factors are going to be pretty bonkers in coming years.Middle Relief: Finding All-Stars in Power RankingsIn this week’s Power Rankings, we made a case for one All-Star per team. Here are the sections for our Nos. 4 and 5 teams, the 39-26 Yankees and 35-32 Mariners, respectively.Yankees last Power Ranking: 3The case for: LF Cody BellingerAaron Judge is hurt, and so you might assume the Yankees lost their best hope to place an outfielder in the American League starting lineup. But, no, Bellinger has the highest fWAR among all AL outfielders. This should be his first All-Star selection since 2019. And we’re singling out Bellinger in part because we assume that everyone already knows that Ben Rice and Cam Schlittler belong on the AL roster. In fact, those two probably should be the starters at first base and on the mound. Max Fried is also in the mix for a roster spot, and don’t sleep on Jazz Chisholm Jr. making it. Chisholm hasn’t been great this year, but the second-base field is pretty weak in the AL, and Chisholm is top-two in fWAR at the position there. — Chad JenningsMariners last Power Ranking: 6The case for: SP Emerson HancockIt wasn’t that long ago that the Mariners were in the pitching-development business, making smart trades for young pitchers and getting All-Star value out of the draft, from the first round to the sixth. And while this was going on, the pitcher with the highest pedigree — Hancock, the sixth pick in 2020 — was looking like a Quad-A starting pitcher or a future middle reliever. He just couldn’t get over the hump.
