MILWAUKEE — The Pittsburgh Pirates made some changes to their lineup against the Milwaukee Brewers, including sitting one of their rookies.The Pirates don't have Esmerlyn Valdez in the lineup in the series finale vs. the Brewers at American Family Field on Aug. 6.Valdez had started the past 33 games in right field for the Pirates since June 28 and had been one of the best hitters.It's a much needed day of rest for Valdez and one that the Pirates hope will get him back on track.Why Valdez isn't Starting vs. the BrewersThe Pirates are trying to find time off for all of their main starters, as they are in the midst of 17 games in 17 days, with this the 14th game of that stretch.Valdez hasn't been out of the lineup since late June and for good reason, as he hit .261/.396/.600 for an OPS of .996 in those 33 games, with 30 hits, seven doubles, 10 home runs, 30 RBI and 26 walks to 50 strikeouts.Jul 20, 2026; Bronx, New York, USA; Pittsburgh Pirates right fielder Esmerlyn Valdez (55) hits a two run home run during the third inning against the New York Yankees at Yankee Stadium.
