TEXAS RANGERS

Rookie pitcher Ian Gibaut was suspended for three games Tuesday, a day after he threw a fastball behind San Diego’s Manny Machado following a grand slam in a dust-up over baseball’s unwritten rules.

Gibaut appealed the penalty imposed by MLB and was active for Tuesday’s game against the Padres. Rangers manager Chris Woodward wasn’t in the dugout — he was suspended one game and served it. The two also were fined.

Gibaut, 26, came in Monday night in the eighth inning after Padres slugger Fernando Tatis Jr. hit a grand slam on a 3-0 pitch off Juan Nicasio with San Diego up seven in a game it eventually won 14-4. Gibaut threw his first pitch behind Machado. The umpires conferred, and Gibaut stayed in the game.
