Things to know about this game
• Despite a rare matchup with the Nats, the Halos could face a pair of familiar foes in relievers Sean Doolittle and Ryan Madson. Washington acquired the two Sunday in a trade with the A's in exchange for Blake Treinen and two prospects. Doolittle and Madson have appeared in a combined 46 career games against the Angels.
• Chavez has appeared in seven career games vs. the Nationals, but Tuesday will mark his first start against the club. He has a 0-0 record and a 3.52 ERA (three earned runs across 7 2/3 innings) against Washington.
• Injuries have limited Doolittle to 21 1/3 innings this season. But among left-handers with at least 300 pitches thrown, his 17.8-percent swinging-strike rate ranks second, just ahead of the Indians' Andrew Miller. Among southpaws with at least 75 opponent at-bats, Doolittle is first with a .154 expected batting average allowed, according to Statcast, based on the quality of contact made against him.
