Corbin Burnes: Everything you need to know

Burnes (elbow) threw a bullpen session Tuesday, Jose M. Romero of the Arizona Republic reports. Burnes has been throwing occasional bullpen sessions since spring training -- Tuesday's session was his fourth -- so there was nothing particularly notable about Tuesday's activity. "He just wants to make sure everything is feeling right, he's duplicating his delivery," Diamondbacks manager Torey Lovullo said of Burnes. The pitcher is still on track to return near or after the All-Star break.

Burnes (elbow) threw a bullpen session Monday, Steve Gilbert of MLB.com reports. Burnes threw a second bullpen session and mixed in curveballs after tossing 15 pitches (all fastballs) last Friday. The plan going forward calls for the right-hander to pitch again this coming Friday then two sessions per week for the next month. Burnes will incorporate all his pitches in those twice-weekly sessions. He estimated to be throwing at about an 80 to 85 percent effort level.

Burnes (elbow) tossed 15 pitches during Friday's bullpen session, Nick Piecoro and Jose Romero of The Arizona Republic reports. It was an encouraging sign for Barnes, with Friday's bullpen session being his first since undergoing Tommy John surgery in June. All 15 of his pitches were fastballs or sinkers, and he reached a top velocity of 91 mph. Barnes' current plan is to toss two bullpen sessions a week, and the 31-year-old right-hander is aiming to make his 2026 debut around the All-Star break in July.
