Pirates vs Diamondbacks Live Stream: Start Time, TV Channel & Real-Time Score Updates for Tonight’s MLB Showdown

The Arizona Diamondbacks open a pivotal three-game home stand against the Pittsburgh Pirates tonight at Chase Field, first pitch 9:40 p.m. ET/6:40 p.m. local. Right-hander Ryne Nelson (1-1, 4.60 ERA) draws the start opposite southpaw Andrew Heaney (3-3, 2.91 ERA) as both clubs try to gain traction heading into June. Why this series matters • Playoff positioning: Arizona (26-27) sits 4th in the NL West but only 2.5 games out of the final Wild Card slot. Pittsburgh (19-35) is buried in the NL Central yet just launched a new era under interim manager Donnie Kelly, going 7-9 since the change. • Memorial Day spotlight: With a light Monday slate, “Pirates vs Diamondbacks” headlines national MLB searches, boosting eyeballs for streaming and live-betting platforms. • Star power: Rookie phenom Paul Skenes (3-5, 2.36 ERA) is slated for Wednesday’s getaway game, while Cy Young candidate Corbin Burnes (3-2, 2.73 ERA) toes the rubber for Arizona on Tuesday. Projected pitching match-ups Game 1: RHP Ryne Nelson vs LHP Andrew Heaney Game 2: RHP Corbin Burnes vs RHP Mike Burrows Game 3: RHP Zac Gallen vs RHP Paul Skenes. Key storylines to watch Diamondbacks’ home dominance: Arizona has won 10 of its last 11 in Phoenix against NL Central opponents, riding a bullpen ranked 5th in MLB in ERA since May 1. Pirates’ run-scoring woes: Pittsburgh averages an MLB-worst 3.04 runs per game and owns a .224 team batting average, putting extra pressure on a starting staff that’s actually top-10 in ERA. Nelson’s audition: With Eduardo Rodríguez on the injured list (shoulder), Nelson can cement a rotation spot after limiting the Dodgers to one run over five innings last week. Heaney’s craftiness: The veteran lefty succeeds with a 90 mph fastball paired with a deep off-speed mix; Arizona hitters own just a .227 average versus change-ups this season. Odds and betting nuggets • Moneyline: Diamondbacks -185 | Pirates +155 • Run line: Arizona -1.5 (+104) • Over/Under: 9.5 runs. Trend to note: The over is 7-2 in the last nine Pirates road games, while Heaney’s last three outings have all cashed the under. Injury report Diamondbacks: LHP Eduardo Rodríguez (shoulder) 10-day IL, INF Ketel Marte (hamstring) day-to-day. Pirates: OF Bryan Reynolds (oblique) out until early June; 3B Ke’Bryan Hayes (back) expected to return for Tuesday’s game. Players to watch • Oneil Cruz, PIT: Posted MLB-record 122.9 mph exit velocity on May 25; leads team with 11 HR. • Corbin Carroll, ARI: Slashing .314/.376/.538 at Chase Field; two multi-hit games versus lefties last week. • Paul Skenes, PIT: Wednesday showdown versus Zac Gallen could be must-see TV for scouts and fans alike.
