Reds pitcher Johnny Cueto continues to enhance his free agency stock after a fast start to the 2015 season, reports CBSSports.com Baseball Insider Jon Heyman.

Cueto, who posted a career-best 2.25 ERA last season, is on pace for another breakout campaign. Although he's 1-2 through four starts, the 29-year-old right-hander owns a 1.86 ERA, a 0.82 WHIP, a 1.93 FIP and a 32:5 K:BB ratio over 29 innings pitched this season.

Cueto, who was unable to come to terms with a new extension before Opening Day, is believed to be seeking a contract worth around $200 million after Nationals starting pitcher Max Scherzer landed a $210 million contract this offseason.
