ANAHEIM, Calif. (Interstat) — For eight innings on Friday night at Angel Stadium, a classic pitchers’ duel between Seattle’s Bryan Woo and Los Angeles’ Reid Detmers produced zeroes and mounting tension. It took a 10th-inning outburst, punctuated by Josh Naylor’s decisive two-run single, for the Mariners to finally break through and secure a 3-1 victory over the Angels in the opener of a three-game series.

A crowd of 44,931 witnessed a masterclass in starting pitching that gave way to a frantic extra-inning finish, with Seattle improving to .500 at 4-4 and Los Angeles falling to 3-5.

The story for the first two-thirds of the game was the dominance of the young starters. Woo, Seattle’s top star, was brilliant, carrying a no-hitter into the seventh inning. His only blemish was a two-out, third-inning single by Oswald Peraza that deflected off right fielder Victor Robles. Woo finished with seven shutout innings, allowing just that one hit while walking one and striking out six. He threw 56 pitches, 20 for strikes, and induced 20 balls in play, commanding the zone with ease.

He was matched nearly pitch-for-pitch by the Angels’ Detmers, who was equally sharp over 6 2/3 scoreless frames. Detmers scattered three hits, walked two and struck out four, keeping a potent Seattle lineup off balance. The Mariners managed only a pair of singles in the fourth and another in the seventh but could not advance a runner past second base against him.

Both bullpens preserved the stalemate through the ninth. Seattle’s Matt Brash struck out two in a perfect eighth, and Andrés Muñoz overpowered the Angels with three strikeouts in a clean ninth. For Los Angeles, Drew Pomeranz, Jordan Romano and Chase Silseth combined for 2 1/3 hitless innings of relief, sending the game to extras deadlocked at 0-0.

The most important part of the game arrived in the top of the 10th. With the automatic runner, Luke Raley, placed on second, leadoff hitter Cole Young immediately drove him home by launching a triple to right field off Angels reliever Brent Suter. After two outs, the Angels opted to intentionally walk Julio Rodríguez to set up a force. The strategy backfired when Naylor, who had one of Seattle’s seven hits earlier, lined a single into right field, scoring both Young and Rodríguez to give the Mariners a commanding 3-0 lead.

The Angels mounted a minor threat in their half of the 10th. Mike Trout, the automatic runner, advanced to third on a groundout and scored on Jorge Soler’s sacrifice fly to right. But Seattle closer Gabe Speier, who earned his first save of the season, ended the game by striking out Yoán Moncada on a challenged call, sealing the 3-1 final.

The win went to Muñoz (1-1), while Suter (0-1) took the loss. The game, which lasted 2 hours and 54 minutes, defied pregame projections. Interstat’s game simulator had projected a 4-3 Seattle win, and its ELO system gave the Mariners a 63.6% probability of victory. However, the combined four total runs fell well under the over/under line of 8, as the pitching dominated far more than expected.

For Woo, the performance was a bounce-back after taking a loss on March 28 against Cleveland despite nine strikeouts. It anchored a combined one-hitter by five Seattle pitchers, who totaled 16 strikeouts. The Mariners’ offense, held to just three hits through nine innings, erupted for four hits and all three runs in the decisive 10th.

The Angels, who managed only Peraza’s third-inning single, saw their offensive struggles continue. They have scored three or fewer runs in five of their eight games this season.

The two teams continue the series Saturday and Sunday in Anaheim before Seattle heads to Texas and the Angels host Atlanta.
