PHOENIX, May 14 \u2014 Arizona Diamondbacks<\/a> left fielder Lourdes Gurriel Jr.<\/a><\/strong> lined a walk-off double in the bottom of the ninth, scoring Christian Walker<\/a><\/strong> from first to give the Arizona Diamondbacks a dramatic 2\u20131 victory over the San Francisco Giants<\/a> Sunday afternoon.<\/p>\n The double capped off a pitchers\u2019 duel between Diamondbacks rookie Brandon Pfaadt<\/a><\/strong> and Logan Webb<\/a><\/strong> of the Giants. Pfaadt tossed five innings, walking three and striking out five while giving up one run. That run came on the lone hit he allowed, which was a solo home run by Giants right fielder Michael Conforto<\/a><\/strong>. Webb, in seven innings, allowed one run on three hits, striking out three while walking three and hitting a batter. Jose Ruiz<\/a><\/strong>, Scott McGough<\/a><\/strong>, and Miguel Castro<\/a><\/strong> combined to pitch four innings of scoreless relief, with a hit off Ruiz and another off McGough being the only baserunners the Giants could muster.<\/p>\n \u201cYou’re always looking for young players to grasp concepts as they need to make some adjustments. Continue to learn and grow, trust the coaching, and then push forward. See how it goes, get the response, and keep pushing the next time,\u201d manager Torey Lovullo<\/a><\/strong> stated after the game with pride in his voice. \u201cBrandon Pfaadt\u2019s outing today is a perfect example of all the things that we believe in. Preparation. Trust. Commitment. He stayed with the plan and sequenced his pitches very well. Fastball command was much improved, and he got us through five innings. If there wasn’t a hiccup with the 10-to-11-pitch at-bat to Conforto, I may have pushed him through six. But overall, I felt like 80-plus pitches, he had done his job. Lovullo also praised the relievers, calling their effort \u201cfantastic.\u201d<\/p>\nDiamondbacks, Giants Offenses Both Held at Bay<\/h3>\n
