TORONTO -- The A's are riding a youth movement through the remainder of the season and beyond, with a focus on collecting young talent capable of forming a contender when a potential new stadium opens in Oakland.
Already, several of these pieces have emerged from the Minors -- notably infielders Matt Chapman, Ryon Healy and Chad Pinder.
Chapman, who entered the year at No. 100 on MLBPipeline.com's Top 100 Prospects list, gained ground in the midseason report released Tuesday, coming in at No. 92.
Chapman, promoted from Triple-A Nashville on June 15, has five home runs since the All-Star break and three in as many days entering Tuesday.
"I just feel like I'm in control of the at-bats, and obviously you can't control the results every time," Chapman said Monday night, "but I feel like I've been putting myself in the best position to have success."

The A's top prospect, middle infielder Franklin Barreto, made big moves, going from No. 52 to No. 37. Right behind him is Oakland's No. 2 ranked prospect, A.J. Puk, who landed at No. 39 on the Top 100 list.
Right-hander Grant Holmes fell off the charts, after being ranked No. 83 in preseason rankings.
The ranking of baseball's top prospects is done by MLBPipeline.com Draft and prospect experts Jonathan Mayo, Jim Callis and Mike Rosenbaum, who compile input from industry sources, including scouts and scouting directors. It is based on analysis of players' skill sets, upsides, proximity to the Majors and potential immediate impact to their teams. Only players with rookie status are eligible for the list. Players who were at least 23 years old when they signed and played in leagues deemed to be professional (Japan, Korea, Taiwan, Cuba) are not eligible.
Among the A's Top 30 list is their 2017 first-round Draft pick, Austin Beck. The outfielder makes his debut at No. 4, with lefty Jesus Lazardo -- acquired from Washington in the Sean Doolittle and Ryan Madson trade -- grabbing hold of the No. 5 spot. The No. 6 spot belongs to Cuban outfield prospect Lazaro Armenteros, with right-handers Daniel Gossett, Logan Shore and Holmes, and catcher Sean Murphy rounding out the Top 10.
