Midway through April, we're still in the very early stages of the 2019 MLB season.
However, for players who are off to particularly terrible starts, it might already be time for teams to start weighing their potential replacement options.
Whether it's a young player who looks like he might need more time in the minors, an offseason acquisition not playing up to his potential or a veteran coming to the end of the line, a handful of players could soon find themselves benched or demoted.
Ahead is a look at seven such players and possible alternatives.
Corbin Burnes, SP, Milwaukee Brewers
Stats: 4 GS, 0-2, 10.70 ERA, 8 BB, 24 K, 17.2 IP
Potential Replacement: Adrian Houser
After working primarily as a starter in the minors, Corbin Burnes joined the Milwaukee Brewers bullpen last year and posted a 2.61 ERA and 1.00 WHIP in 30 relief appearances.
With Wade Miley and Gio Gonzalez departing in free agency, the Brewers hoped he would make a smooth shift back to starting and fill a slot in the rotation.
Instead, the transition has been a disaster.
